Abstract
A system and method of reducing VSAT apertures via satellite MIMO is disclosed. The system and method comprise a first hub antenna configured to receive a first return signal from and to transmit a first forward signal to a first adjacent satellite, a second hub antenna configured to receive a second return signal from and to transmit a second forward signal to a second adjacent satellite, and a hub station configured to determine time delay and frequency shift between the first return signal and the second return signal after they are received by the first hub antenna and the second hub antenna, and to apply the determined time delay and frequency shift to one of the first forward signal and the second forward signal prior to transmitting them so the first forward signal and the second forward signal are time- and frequency-aligned when received at the remote ground terminal via the first adjacent satellite and the second adjacent satellite, wherein the first return signal and the second return signal are transmitted from the remote ground terminal to the first hub antenna and the second hub antenna via the first adjacent satellite and the second adjacent satellite. Similar time- and frequency-aligning can be achieved at the remote ground terminal using polarized signals transmitted from the remote ground terminal.
